M2TS to WebP Converter

M2TS to WebP — Should You Extract Your Still as WebP?

This tool pulls a single still frame (or a batch of frames) out of an M2TS video and saves it as a WebP image. M2TS is the BDAV MPEG-2 transport stream that Blu-ray Discs and AVCHD camcorders use to carry H.264/MPEG-4 AVC video, so the source frame is high-resolution. The question is which still format to export it as: pick WebP when you want the smallest file that keeps photo quality and can carry transparency; pick JPEG for maximum compatibility with old photo apps; pick PNG for a pixel-exact graphic. The short answer for anything heading onto a website: WebP.

WebP vs JPEG vs PNG for a Video Still

When to Pick WebP

• You are putting the still on a website or in an app and want the smallest file at photo quality — WebP lossy is 25-34% smaller than the equivalent JPEG, per Google's own measurements.
• You need a smaller-than-PNG still that still carries transparency or an alpha channel.
• Your audience is on modern browsers (Chrome, Firefox, Edge, Safari 14+) — about 96% of the web.

When to Pick JPEG or PNG Instead

• Pick JPEG when the file must open in older photo software, a legacy print workflow, or a device that predates WebP (Safari 13 and earlier, Internet Explorer). Use M2TS to JPEG for that route, which covers the frame-by-frame extraction in depth.
• Pick PNG when you need a pixel-exact, never-recompressed still — a screenshot with sharp text or a graphic overlay — and don't mind the larger file. WebP lossless avoids re-compression too, but PNG is the safer master format for archival. See M2TS to PNG.

How to Convert M2TS to WebP

1. Upload Your M2TS File: Drag and drop the .m2ts (or .mts) file onto the page, or click "+ Add Files" to browse. You can queue several clips; each is processed with the same settings.
2. Choose Frame Selection: Under Frame Selection, pick Specific Frame and type a timestamp into the Time (seconds) box to grab one still, or pick Multiple Screenshots and set a Capture Rate to export a sequence across the clip.
3. Set Lossless and Quality Preset: Leave Lossless? on No with Quality Preset at Very High for a small, photo-quality WebP, or switch Lossless? to Yes for a pixel-exact still that still beats PNG on size. Keep Preset Resolutions on "Keep original" to retain the full HD frame.
4. Convert and Download: Click "Convert" and save the WebP. A single frame downloads as one .webp; a multi-frame export downloads as a ZIP of numbered images. No sign-up, no watermark.

Frequently Asked Questions

Is the WebP output a still image or an animated WebP?

A still image. This tool extracts frames from the M2TS video and saves each one as a standalone still WebP — Specific Frame produces one .webp, and Multiple Screenshots produces a ZIP of individual stills. It does not assemble the frames into an animated WebP. If you want a short looping animation instead, convert the clip to an animated format with a tool built for that, such as MP4 to WebP on an MP4 export of the footage.

Will I lose quality going from M2TS to WebP?

In lossy mode, slightly — WebP re-compresses the already-compressed H.264 frame, but at the Very High Quality Preset the loss is hard to see, and the result is 25-34% smaller than the equivalent JPEG at matched quality. For a pixel-exact still with no second round of loss, switch Lossless? to Yes; lossless WebP keeps every pixel and is still about 26% smaller than the same image saved as PNG.

Why does my extracted still have horizontal comb lines?

That is interlacing combing. Much AVCHD camcorder footage is recorded 1080i, where each frame is built from two fields captured a moment apart. On a moving subject the two fields don't align, so a still shows a horizontal comb pattern — and the WebP just stores those pixels faithfully. Land your timestamp on a low-motion moment to avoid it; progressive sources (1080p/24p/60p) and most Blu-ray content are not interlaced and won't comb.

Can WebP keep a transparent background from the video?

A video frame is fully opaque, so there is nothing transparent to preserve — the extracted still has no alpha to begin with. WebP supports transparency (in both lossy and lossless modes), which matters if you later edit the still and erase a background; JPEG can't store that, but WebP and PNG can. If transparency is the goal, export as WebP or PNG and edit the alpha afterward.

How big will the WebP file be compared to the source video?

Tiny. You're saving one frame, not the whole clip, so a single still is a fraction of the M2TS file's size. In our testing, a 1920×1080 frame from a 1080i AVCHD clip exported at the Very High preset (lossy, not lossless) lands in the low hundreds of kilobytes — noticeably smaller than the same frame saved as JPEG, and a small fraction of a lossless PNG of the same frame.

Which browsers and apps can open the WebP it produces?

The output is a standard WebP still. Every current major browser opens it natively — Chrome 32+, Firefox 65+, Edge 18+, and Safari 14+ (macOS Big Sur / iOS 14 and later), which together cover roughly 96% of browsers. Windows 10/11 Photos and macOS Preview also display WebP. Only legacy clients like Internet Explorer 11 and Safari 13 and earlier need a JPEG or PNG instead.

Are my uploaded files kept private?

Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
